Predicting MIGS Success

In this interview from AGS 2017, Dr. Davinder Grover shares how to predict success following a minimally invasive glaucoma surgery (MIGS) procedure. His top recommendation is to observe the episclera for a blanching of blood caused by a washout wave of BSS, a technique called episcleral venography he developed with his colleague Dr. Ronald Fellman. Additionally, disease stage can be used as a proxy for success: Dr. Grover has found that 6-month cumulated failure rates in those with advanced visual field loss approached 90% following GATT (gonioscopy-assisted transluminal trabeculotomy), compared with only 20% in those with mild disease.
